This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium ion batteries (LIBs) are ubiquitous for applications in consumer electronics, electric vehicles, and grid-scale energy storage. Despite rapidly increasing demand, modern LIBs face significant challenges with regards to their safety and energy density. Additionally, the rigid nature of existing LIBs precludes their use in emerging applications in flexible/wearable electronics. Polymeric materials promise to address many of the issues facing LIBs, yet the existing polymers used commercially fall short of this goal. In this work, we design functional polymer materials to address three major challenges for next-generation LIBs. We explore the structure-property relationships of these polymer architectures in the context of ion transport, mechanical properties, and electrochemical performance. In the first project, a new polymer electrolyte is designed to replace the flammable liquid electrolyte in conventional LIBs. We study the effect of lithium ion coordination in polymer electrolytes and discover a modified polymeric backbone that loosely coordinates to lithium ions. The loose coordination of this new polymer electrolyte enables an improved lithium transference number of 0.54, compared to 0.2 achieved in conventional polymer electrolytes. This polymer electrolyte is demonstrated to operate effectively in a battery with a lithium-metal anode. In the second project, the learnings of the lithium coordination environment from the first project are used to design a multifunctional polymer coating to stabilize high energy density lithium metal anodes. We combined loosely-coordinating fluorinated ligands dynamically bonded with single-ion-conductive metal centers. The resulting supramolecular polymer network functions as an excellent lithium metal coating, allowing for achievement of one of the highest-reported coulombic efficiencies and cycle lives of a lithium metal anode. A systematic investigation of the chemical structure of the coating reveals that the properties of dynamic flowability, single-ion transport, and electrolyte blocking are synergistic in improving Li-metal coating performance. This coating is applied in a commercially relevant lithium metal full-cell and increases the cycle life over two-fold compared to an uncoated anode. The final project uses supramolecular polymer design to create ultra-robust ion transport materials. We show that when soft ion conducting segments are combined with strong dynamically bonded moieties in the polymer backbone, the ion transport properties can be decoupled from the mechanical properties. This decoupling enables for the creation of polymer electrolytes with extremely high toughness and high ionic conductivity. These supramolecular materials enable the fabrication of stretchable and deformable batteries that demonstrate respectable energy density even when stretched to 70% of their original length. Overall, the work demonstrated in this thesis provides a robust understanding towards designing polymer networks with tunable ion transport and mechanical properties. Additionally, the polymer materials demonstrated here provide promising avenues toward improving the safety, energy density, and flexibility of LIBs.

Book excerpt: Safety of Lithium Batteries describes how best to assure safety during all phases of the life of Lithium ion batteries (production, transport, use, and disposal). About 5 billion Li-ion cells are produced each year, predominantly for use in consumer electronics. This book describes how the high-energy density and outstanding performance of Li-ion batteries will result in a large increase in the production of Li-ion cells for electric drive train vehicle (xEV) and battery energy storage (BES or EES) purposes. The high-energy density of Li battery systems comes with special hazards related to the materials employed in these systems. The manufacturers of cells and batteries have strongly reduced the hazard probability by a number of measures. However, absolute safety of the Li system is not given as multiple incidents in consumer electronics have shown. Presents the relationship between chemical and structure material properties and cell safety Relates cell and battery design to safety as well as system operation parameters to safety Outlines the influences of abuses on safety and the relationship to battery testing Explores the limitations for transport and storage of cells and batteries Includes recycling, disposal and second use of lithium ion batteries

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The ever-growing energy demand of modern society calls for application of renewable energy sources. Among various renewable energy sources, solid-state lithium-ion battery (SSLIB) has become a rising star due to its high intrinsic safety, high energy density and sustainability compared with traditional liquid lithium-ion batteries. In the development of SSLIBs, solid polymer materials have attracted intensive attention due to their many desirable properties such as processibility, sustainability and low cost. This dissertation focused on the understanding and development of novel polymer materials for SSLIBs. Chapter 2 discusses a new strategy of modifying the structure of polymer electrolyte to increase its ionic conductivity while preserving other desirable properties, such as oxidative stability by utilizing flexible, oxidatively stable aliphatic segments. Hydrogenated nitrile butadiene rubber (HNBR) and nitrile butadiene rubber (NBR) was blended with lithium bis(trifluoromethanesulfonyl) imide (LiTFSI) to create polymer electrolytes. Their physical and electrochemical properties were characterized in detail. It was found that HNBR:LiTFSI has 3.1×10-7 S/cm at room temperature. Compared with unplasticized PAN:LiTFSI and unsaturated NBR:LiTFSI, ionic conductivity of HNBR:LiTFSI is significantly improved, while the oxidative stability of PAN:LiTFSI is preserved. Chapter 3 focuses on developing a more reliable measure of oxidative stability in polymer electrolyte. Oxidative stability is an important and widely referenced property of battery electrolytes, yet its measurement is often poorly conducted. A capacity-based electrochemical method that measures the reversibility of the system was developed. The absolute stability threshold of PEO/LiTFSI (3.6V vs. Li/Li+) and HNBR/LiTFSI (3.7V vs. Li/Li+) was measured with reversibility test, and further verified by a non-electrochemical method. Chapter 4 explores the possibility of expanding the role of polymeric materials from electrolyte to cathode. Anew cathode chemistry for thin-film battery was proposed and examined. A vapor deposited polymeric charge transfer complex (CTC) cathode, P4VP-ICl was investigated. Spectroscopic, stoichiometric, and electrochemical properties of the CTC complex was collected and analyzed. P4VP-ICI LIPON Li thin film battery was demonstrated on both rigid and flexible substrates. The flexible P4VP-ICI LIPON Li battery can be bent 180ʻ without losing electrochemical performance"--Pages x-xi.

Book excerpt: The incorporation of heteroatoms into carbon-based systems for the modification of functional materials is an exciting field of study. Of relatively recent interest is the addition of phosphorus to traditionally all-carbon systems, which is possible due to the similarities between the two elements, affording unique chemical and electronic properties. Herein, permutations of o-hydroxyarl phosphines and phosphine oxides were developed for two distinct functions. The compounds start from similar, readily available materials, and utilize similar syntheses.Bis(phosphonate) compounds were generated from aryl diols such as catechol and 2,3-dihydroxynaphthalene. These bis(phosphonate)s acted as chelates to main group elements like boron and phosphorus, and lithium salts were generated. These salts, designed to parallel lithium-ion battery electrolyte salts, had flame retardant properties. Therefore, these materials could potentially act as bifunctional electrolytes: flame retardant ions for lithium-ion batteries (FRIONs). This second generation of FRIONs was generated in good yields from commercially-available materials, and exhibited good flame retardant properties. Using a bottom-up design, modifications were made to these ligands to impart properties, such as solubility, to the resultant main group chelates and lithium salts. Several such modifications were made corresponding to the third generation of FRIONs.A new synthetic route utilizing a Lewis acid was developed for the synthesis of 1,3-benzoxaphosphole (BOP) compounds (Chapter 4), and a new reduction was developed for the generation of o-hydroxyarylphosphines, common BOP starting materials (Chapter 3). These methods allowed for isolation of previously synthesized BOP compounds (and starting materials) in nearly quantitative yields, and the generation of BOP compounds developed from FRION precursors. Using the new synthetic method of BOP synthesis, stepwise polymerization reactions were performed which resulted in the generation of several BOP-based oligomers. The choice of phosphine starting material and linker significantly impacted the results of the polymerization reaction. Using a terephthalate linker resulted in low degrees of polymerization due to p-stacking interactions, while fluorene linkers resulted in decomposition of the BOP unit due to slow reactivity. These new synthetic procedures were also used to generate novel BOP materials with unique reactivity (Chapters 7,8), and were utilized in attempts to generate other group 15 heterocycles (Chapter 6).

Download or read book Synthesis of Conductive Nanoparticles and Their Applications as Thermal Responsive Polymer Switching Composites for Battery Safety written by Mingqian Li and published by . This book was released on 2021 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Great advances have been made in lithium-ion batteries (LIBs) since they were first invented in 1970s. High energy density, fast charging rate and wide temperature operation have been achieved, which paves their way to broad applications in portable electronic devices, electric vehicles (EVs) and grid energy storage. However, despite their rapid performance improvement in recent years, the safety issue is still the sword of Damocles of LIBs due to their inherent flammability and thermodynamically non-equilibrium operation, which can lead to catastrophic consequences once they are exposed to extreme conditions such as overheating, shorting or cracking. In this thesis, strategies to foreclose potential safety hazards in LIBs have been explored in the level of material design. By integrating thermo-responsive polymer switching composites (TRPS) into the LIBs, it can successfully inhibit the heat generation when cells suffer from thermal abuses, which can prevent the occurrence of thermal runaway. To make TRPS materials more attractive in practical applications, we synthesized nanospiky Ni as the conductive fillers for the TRPS materials, which not only successfully reduce the thickness and improve the energy density of cell equipped with TRPS, but also boost the electrical conductivity of TRPS. To make TRPS materials can be seamlessly transferred to the industrial scale, we developed a solvent-based fabrication method to prepare PE-based TRPS materials on current collectors which can be directly integrated into the electrodes production process. We revealed that the size distribution range of conductive fillers plays critical role for the temperature response capability. The processing parameters such as substrate temperature, drying out time can affect the distribution of fillers in the polymer matrix, which determines the properties of TRPS films. We obtained TRPS films in a large size with uniform quality and demonstrated the protective effect in pouch cells. We also designed a general synthetic method to obtain carbides with the desired morphology. Systematic investigations were conducted by characterizations and calculations to understand the phase and morphology evolution process of as-prepared tungsten carbide. A spherical tungsten carbide was synthesized and employed as fillers for TRPS, which boosts the conductivity of WC-based TRPS materials. Overall, this dissertation offers a deep understanding and guidance for designing and fabrication of TRPS materials, taking one step further for the industrial production and real applications of TRPS to provide more safety protection of LIBs.
